... the #4 had a slot in the coupler shank that was behind theI didn't mention that *&%$### subatomic-sized cylindrical filler
piece that has to be placed inside the spring sunokt because I felt I
was already pushing the envelope already in attempting to describe the
#4's venerable but unusual coupler shank centering arrangement. If
memory serves, this tiny cylinder was also a later addition by Kadee
some years following Kadee's shift to magnetic couplers, while other
aspects of the design remained unchanged. BTW, the coupler seems to
operate quite well if this cylinder is left out, i.e. as in, it has
already flown off the bench into a netherworld.
As implied, assembling the couplers with this miniscule little piece
was and still is no picnic. Once assembled, the coupler box/coupler is
treated with the highest respect.
